The Lattice Boltzmann methods for solids (LBMS) are specific methods based on the lattice Boltzmann methods (LBM). LBM are a group of numerical methods that are used to solve partial differential equations (PDE). These methods themselves relying on a discretization of the Boltzmann equation. When the PDE at stake are related to solid mechanics, this subset of LBM is called lattice Boltzmann methods for solids. The main categories of LBMS are relying on:
The LBMS subset remains highly challenging from a computational aspect as much as from a theoretical point of view. Solving solid equations within the LBM framework is still a very active area of research. If solids are solved, this shows that the Boltzmann equation (BE) is capable to describe solids motions as well as fluids and gases: thus unlocking complex physics to be solved such as fluid-structure interaction (FSI) in biomechanics.
Proposed insights
Vectorial distributions
Wave solvers
Force tuning
Introduction
This idea consists of introducing a modified version of the forcing term[3] into the LBM as a stress divergence force. This force is considered space-time dependent and contains solid properties[Note 1].
Some results
Force tuning has recently proven its efficiency with a maximum of 5% of error in comparison with standard solvers for solids studies.
